Problem with nested functions - functions nested too deeply in source code
Hi all! I¹m just implementing the Ullmann¹s algorithm for searching subgraph isomorphisms in graphNEL objects. The algorithm is running with smaller graphs, but when I¹m calling it i get an R error message saying that functions are nested too deeply in source code. I found out that the problem is in the so called refinement procedure of the algorithm which consists of 10 different functions,

[LLVMdev] Problems when refining type
Hi I'm using the llvm-c wrapper, and trying to build some recursive types (using released 2.3). I get an assert on trying to create a second opaque pointer type after refining a first. The first time through creating an opaque pointer type, a new type is created and returned from PointerType::get, but the second time, ValueType (the opaque type) is found in the PointerTypes map, which seems

Another good optimization (for PPC only, though)
Using the PPC frsqrte and fres instructions, I got the percentage time take in the smoothing code in _vp_compute_mask() down from 13.64% to 1.88% of the running time. In my local copy of Vorbis I have a fast_math.[hc] in vorbis/lib and have a _fast_sqrt() inline in fast_math.h. If anyone else wants to try it out, it follows. I can currently encode my test file (the first 15 seconds of

anova model refinement/clustering question
Hi, I am trying to refine models of a continuous response variable and a number of categorical predictor variables. I know of some model refinement tools available in R that help in the selection of model terms like dropterm and addterm from MASS etc. However, I would also like to try to refine the model by 'coalescing' some levels of some of the predictor factors. Is there a standard

Notice also Additionally, since you're implementing a "mean" function you are testing against R's mean, you might want to consider that R uses a two-pass calculation[1] to reduce floating

Announcing another R search engine
Hello all, I wanted to announce a new R search engine I made that covers all the major R mailing lists, CRAN, r-project.org, and more. Results are tabbed, so you can refine the search. Current refinements include searching just the mailing lists, searching just introductions, and searching the web for source files ending in .R. Please send comments and suggestions. If you want to add sites to

[Patch 0/4] Refining Xsave/Xrestore support - Version 2
Hi, Keir, The following patches refines Xen support for CPU Xsave/Xrestore support. There are four patches included. Patch 1/4: Cleaning up existing Xsave code in Xen. Replace xfeature_low and xfeature_high with a u64 variable xfeature_mask. In structure hvm_vcpu, rename xfeature_mask to xcr0 Provide EDX:EAX with all bits set to 1 for XSAVE and XRSTOR as spec recommends

Possible soundness issue with available_externally (split from "RFC: Add guard intrinsics")
...not inline @foo(), and instead re-link the call site in @main to some non-optimized copy (or differently optimized copy) of @foo, then it is possible for the program to have the behavior {print("Y"); print ("X")}, which was disallowed in the earlier program. In other words, opt refined the semantics of @foo() (i.e. reduced the set of behaviors it may have) in ways that would make later optimizations invalid if we de-refine the implementation of @foo(). The above example is clearly fabricated, but such cases can come up even if everything is optimized to the same level. E.g. one...

Crontab offers many refined facilities for Western calendaring, but none for traditional Eastern-- lunar-- designations. So for example, if one wants specify regular occurring events on full moons or on new moons, there is no way to do this. Emacs (a text processor!?) accomplishes this.

using R to perform a word count - syntax refinement and incorrect number of dimensions error
Hello, I am hoping someone can advise me regarding an error message I received and if needed, refine some syntax. I am wanting to calculate the word count for each row of a dataframe. Below, I have 3 variables ("V3.PD", "V3.HD", "V3.LP") which I want to obtain a word count for, by each row which contains these variables. Any assistance is much appreciated, Bob
